How To Use a Fire Extinguisher in 4 Steps
Learn how to use a fire extinguisher safely in 4 simple steps using the PASS method. Understand how to operate a fire extinguisher, when it is safe to use one, and when you should evacuate and call for emergency assistance.
🔥 Why Knowing How to Use a Fire Extinguisher Matters
A small fire can develop into a serious emergency within a very short time. Knowing how to use a fire extinguisher can help a trained person respond quickly to a small, manageable fire before it grows or spreads.
However, a fire extinguisher should never be considered a replacement for emergency evacuation, fire prevention, fire detection systems or professional firefighting. The first priority during any fire emergency is always the safety of people.
Before attempting to fight a fire, make sure the fire is small and contained, the correct type of extinguisher is available, there is a clear escape route behind you, and you have been trained or are otherwise competent to use the equipment.
🧯 What to Do Before Using a Fire Extinguisher
Before learning the four steps, it is important to understand that not every fire should be fought with a portable fire extinguisher.
Check These Conditions First
- 🔥 The fire should be small and in its early stage.
- 🚪 You must have a clear escape route behind you.
- 🧯 Use an extinguisher suitable for the type of fire.
- 👨🚒 You should be trained or competent to use the extinguisher.
- 🌫️ Avoid attempting firefighting if smoke or heat makes the situation unsafe.
- 📞 Raise the alarm and ensure emergency assistance has been contacted according to your site's emergency procedure.
🧯 How To Use a Fire Extinguisher in 4 Steps
The commonly taught method for operating many portable fire extinguishers is remembered using the word PASS. The four steps are:
Pull the Pin
Pull the safety pin or remove the safety device according to the extinguisher design. This allows the extinguisher to be discharged when the handle is operated.
Keep the extinguisher upright and maintain awareness of your escape route.
Aim at the Base of the Fire
Point the nozzle or hose toward the base of the fire, rather than directly at the flames.
The objective is to direct the extinguishing agent toward the source of the fire.
Squeeze the Handle
Squeeze the operating handle to discharge the extinguishing agent.
Follow the manufacturer's instructions and maintain a safe position while operating the extinguisher.
Sweep Side to Side
Move the nozzle or hose in a controlled side-to-side sweeping motion across the base of the fire.
Continue only while it remains safe to do so and according to the extinguisher manufacturer's instructions.
📝 PASS Method for Fire Extinguishers
The four steps are often remembered using the acronym PASS.
🔥 Choose the Correct Fire Extinguisher
Different fires require different extinguishing agents. Using the wrong type of extinguisher can be ineffective and, in some situations, dangerous.
Fires involving materials such as wood, paper, cardboard and some textiles require an extinguisher appropriate for that fire classification.
Fires involving flammable liquids require an extinguisher suitable for the specific fire classification and fuel.
For energized electrical equipment, use an extinguisher that is specifically suitable for electrical fire situations and follow the manufacturer's instructions.
Commercial cooking oil and fat fires require extinguishing equipment specifically designed for these hazards.
